I started seeing errors in my CI after [latest xarray release](https://github.com/pydata/xarray/releases/tag/v2024.02.0). See, e.g.,

https://github.com/COSIMA/regional-mom6/actions/runs/7957078139/job/21719091616#step:7:226

After I added a [compat for xarray](https://github.com/COSIMA/regional-mom6/pull/98/commits/46ca91d2ac91ab57371f94108f18549aaa7040cf) to preclude the latest release the error went away. See:

- [ ] Complete example — the example is self-contained, including all data and the text of any traceback.
- [ ] Verifiable example — the example copy & pastes into an IPython prompt or [Binder notebook](https://mybinder.org/v2/gh/pydata/xarray/main?urlpath=lab/tree/doc/examples/blank_template.ipynb), returning the result.
- [x] New issue — a search of GitHub Issues suggests this is not a duplicate.
